SPRING ACTUATED DISK PROJEQTOR Filed Dec. 29, 1950 fr; vents)" Na r-if/rv hub er" Patented May 13, 1952 SPRING ACTUATED DISK PROJECTOR Martin Huber, Munich, Germany Application December 29, 1950; Serial No. 203,279 I InGermanyJanuaryihl SSO 1 My invention relates to games and particularzy to a device for shooting or sliding a disc simulating a disc such as is used on a shuflle board or a stone such as is used in curling.

The principal object of my device is to provide a disc shooting apparatus of simple character which is adapted to be clamped to a table top. board or the like, along which the discs are to be slid, and by means of which said discs may be shot at a desirable velocity and aimed as desired,

I accomplish these and other objects by means of the novel elements and the combinations and arrangements thereof described below and illustrated in the accompanying drawing in which-- Fig. 1 is a plan view of my device with the throwing lever pulled back into a position from which it may be released to shoot the disc;

Fig. 2 is a front elevation view of the device with the throwing lever vertical;

Fig. 3 is an elevation view of the device as it may be applied to a figure simulating a human being;

Figs. 4 and 5 are sections of Fig. 2 in the plane 4-4 showing the disc holding means in closed and open position, respectively; and

Fig. 6 is a sectional view of a modification.

Referring to the drawing- My device comprises a base member I which is adapted to be secured to a smooth board or table top 2 by means of a clamp 3. Pivotally secured at 4 to the base I is a movable element 5 having an arm 6 by means of which it may be swung about the axis of its pivotal connection to the base plate. The element 5 carries the upright element I. Secured to the element 7 adjacent the top thereof, is a bearing 8 having a horizontal axis on which the pendulous lever 9 is mounted to swing. An element I is secured to the axis of the lever 9 and a tension spring I I is stretched between a pin I2 at the bottom of the element I U and a pin I3 secured to the vertical stand 1 near the bottom thereof. The spring I I is normally under some tension and normally holds the pendulous lever 9 in a vertical position, as shown in Fig. 2.

The preferred form of disc is shown at I4 in Figs. 1-5, inclusive, and is provided with an upright handle I5. Pivotally secured at I6 to the lever 9 near the bottom thereof is a movable jaw or gripping member I! having an arcuate recess I8 therein adapted to embrace the handle I of the disc and hold it against the side of the lever 9 forming a fixed jaw, as best shown in Fig. 4. The movable jaw is normally held in the posi- 1 Claim. (Cl. 124-7).

tion shown in Fig. 4 by means of a spring I9 which is secured to the lever 9 at 20 and also at the pin 2| intermediate its ends. The free end of the spring I9 extends through a hole in the movable jaw IT, as best shown in Figs. 1, 2, 4 and 5.

In Fig. 3, the upright element I has been given the form of a man, as shown at 22, having an arm 23, which is analogous to the lever 9, and which is pivotally connected to the form of the man at 24. The arm 23 functions exactly like the lever 9 and has a spring I9 secured thereto identical with the spring I9, shown in Figs. 1 and 2. A movable jaw 25, in all respects similar to the movable jaw I1, is pivotally secured at 26 to the bottom of the arm 23, and there is an extensionZ'I at the lower end of the arm, forming a fixed jaw, which cooperates with a depending portion 28 of the movable jaw (see also Figs. 1 and 2) to grip the handle I5 of the disc therebetween. Instead of using a tension spring, such as shown at II in Figs. 1 and 2, in the embodiment shown in Fig. 3, a torsion spring 29 is used (see Fig. 6). One end of the torsion spring is connected to the arm 23 by means of a pin 30 and the other end thereof is connected to a pin 3I afiixed to the body of the man 22. This spring is not normally under stress when the arm 23 is vertical but when the arm 23 is pulled back into the position shown in Fig. 3, the spring 29 is wound up so that, when the arm is released the spring 29 imparts a quick swinging movement to the arm 23 in a counter-clockwise direction. The spring I I, shown in Figs. 1 and 2, functions in the same way. That is to say, when the lever 9 is pulled into the position shown in Fig. 1, the spring I I is stretched, and when the lever 9 is released it imparts thereto a quick swinging movement in a counter-clockwise direction, as viewed from the right hand side of either Fig. 1 or Fig. 2. Each spring functions as a brake or damper on the movements of the lever or arm to which it is attached and brings it back to its normal vertical position after a few oscillations.

In operation, the lever 9 or the arm 23 is pulled back by the player into the position shown in Fig. 1 or 3. The handle I5 of the disc is then inserted in the jaws, the direction in which the disc is to be shot is adjusted by means of the handle 6 and the lever 9 or the arm 23, as the case may be, is released. When the lever or the arm reaches an approximately vertical position; the movable jaw I'I strikes the stop 32 which causes the movable jaw to swing about its pivotal connection I6 into the open position shown in Fig. 5 and to release 3 the disc M. The force with which the disc is shot may be varied, as desired, by varying the distance which the lever or arm is pulled back before it is released.

While I have described my invention in its preferred embodiment, it is to be understood that the words which I have used are words of description rather than of limitation and that changes, within the urview ofthe appended'clairn may be made without departing fromthe true scope and spirit of my invention in its broader aspects.

What I claim is:

A game device for shooting a, discsimulatingi a curling stone and having an upstanding handle thereon; said device comprising a basefan upright element, means pivotally seouring saidgeleel;

ment to said base to move about a verticalam a lever, means pivotally connecting said l e er to said upright element to swing ab'out a 7 onefof'saidgjaws,for automatically releasing said disc when said lever reaches a predetermined point during the swinging movement thereof. HUBER, MARTIN.
